How do I delete a marker on Google Maps?

I only know of one way:

Right click and click 'delete me'

How else can I delete markers on Google Maps?

This is my code now:

GEvent.addListener(marker, 'mousedown', function(e) {
    alert(e)
    if (e.button == 2){
    alert('sss')
    map.removeOverlay(marker);
}

When i right-click, it alerts (40.23141543543321,114.3214121421); when I look at the API, I see this:

mousedown(latlng:GLatLng) 

so I think that e is not an event, but a 'GLatLng'

If I use the 'singlerightclick', nothing happens when i right-click.

This is my full code:

I thought I figured it out with this:

GEvent.addListener(map, 'singlerightclick', function(point, source, overlay) {
    map.removeOverlay(marker);
        });

but no, this removes the marker no matter where I click on the map.

I think I have it now:

GEvent.addListener(map, 'singlerightclick', function(pixel,tile, marker) {
    if(marker)
    map.removeOverlay(marker);
        });

According to this link you can simply do

marker.setMap(null);
